In short, could we slap a Qi-compliant coil in our Nexus 10, wire it to the battery, and win?
The coil itself is pretty thin from what I've seen, and there is a bit of room in-between the battery and back plastic (the people with creaky and buckling cases should know about this).
I don't know if there's an actual control board that is needed, but perhaps the coil could be hooked either directly to the battery, or even through USB (that way you can be notified of charging). If a control board is needed, then this might be a bit harder than expected, unless the board itself is pretty thin too.
It looks like someone's managed to do something similar to a Nexus 7 already and had good results (even enters docking mode): http://forum.xda-developers.com/showthread.php?t=2070851
Edit: Instead of routing the coil to the USB or battery directly, we could even hook it to the Pogo pin area, like the person did for the N7 coil mod above.
I'm willing to give this a try, but may have to wait a few weeks till I can get the funds for a coil and for it to ship to me.

According to a-post-at-techchrunch-i-cant-link-to-cause-im-a-noob, the Nexus 10 has Qi already... is it wrong? I haven't opened my Nexus 10 to check
I have openned up my Nexus 10 and dont remember anything for wireless charging being there.
I saw someone mod the Galaxy nexus to enable this sort of thing and from what I remember you should be right Espionage, just as simply as you think. And yes there is room to do it.

I can find no reference to the device on the offical Qi website. This makes me highly skeptical that Qi is already present on the N10, perhaps they confused it with the N4?
Search for yourself if you'd like: http://www.wirelesspowerconsortium.com/products
As slow as the Nexus 10 already charges with it's stock USB cable... do you really WANT to charge it with Qi? :laugh:
You might have to charge it for a week from 0% to get to 100%
Any further developments?
Hey Guys!
Is there any further developments on this possibility? :fingers-crossed:
Why not just use a pogo cable.... you would have to plug in a charging pad anyway.
Nexus 10 Wireless Charging Solution
I know it's been some time but I'm kind of surprized nobody posted a solution yet. I just had a Nexus 10 open and noticed not for the 1st time the pogo pins at the bottom that Google never even put to use. I can't even find an aftermarket docking station for it. We aren't talking about Apple here. Anyways the closest I've seen is a magnetic pogo pin charging adapter cable probably sold mostly to people who broke their USB ports. It seems nobody picked up on sewermike's comment. They DO have pogo pins and with a wireless coil (2-4 chained together) you could wire them to the + and - of the pogo pin cable easily. Also if you have access to old Nexus 2nd gen back covers you can get them there or on eBay cheap. It might be slow like TheAltruistic says but if you have a wireless device charging coffee table which I'm seeing more and more you can just set it on that. If I have time I'll do video or at least post my results.
ive got the pogo cable, if you can buy it do so - its well worth it, i think i paid £15 and i totally stand by it.
as for wireless charging, you can get wireless charging receiver cards that plug into the micro usb port, with this you can either plug it in and bend the cable around the tablet and hide it inside the case or plug it in and have it hang outside, you just rest the card on the charger.
please remember that is isnt a perfect solution as the card will get hot and overheat and stop charging or you'll spend all day charging the tablet.
i use to wirelessly charge the nexus 10 but id rather stick the pogo in

Has anybody noticed that the Play store listing for the Nexus 10 only lists the tablet?
Maybe they wanted to save a few bucks and figured that we'd all have phones with a charger cable already, but it's kinda lame that we'd be paying $400+ for a tablet and we won't even be getting a charger with it. I'm going to have to buy a separate cable for it myself; I kinda want to charge both my tablet and my GNexus at the same time.

I would hope that the listing isn't completed for the box because it's not out yet. I'm hoping that it uses a 2A charger, in which case most people don't have so they would supply it.

It follows the policy for Amazon Kindle HD 8.9, where no charger is included but it includes the micro USB charging wire. Also, Nexus 4 includes all the accessories including charging wire and the charger.

I'll be amazed if they don't supply a charger, i think it more a case of they are not listing it because of regional differences, I got a Sony Xperia S Tablet and noticed that the charging accessories changed for different countries, some would have just a socket to usb convertor, but i got like a mini laptop AC brick as we use 240v in the UK, not 120, so best to just leave it off for now.
I will be interested to see if they charge through the microUSB or via a magnetic charger as standard, and if they charge from MicroUSB, how much the magnetic charger would be

Does the Nexus 10 support wireless charging too? That's pretty cool if so. I think about now is the cue for IKEA and the like to start producing high-end tables which automatically charge anything on top of them. Then you can truly be wireless (well, the table would have to be plugged in, but the odds are you could hide the wire from sight). Since the table is powered, they might as well give it a backlit surface, too. Now that would be a table.

I've not heard anything about it, and Google would be shouting about it if it did, so i'd say it doesn't unfortunately.
I was hoping to start a little project on my N7. I love induction charging and want to set it up on my nexus 7. I was wondering if anyone who has gone through this/know about it/enjoy posting could give me some advice,
Most specifically:
Best dock+backcover combo
Thinnest coil plus chip
Fastest charging
Thanks in advance everybody, can't wait to hear your 2 cents!!

I haven't actually seen anybody fully implement inductive charging yet. However, this guy started doing inductive charging:
https://plus.google.com/u/0/101739011161245720271/posts/fAse7vGmc3q
Well, one easy way of doing it would be to buy a Qi standard inductive charger and a Qi standard inductive charging case (for example, the Palm Pre Touchstone case) and then pull the internals out of the donor case and fit them inside a Nexus 7 case. There's a small amount of soldering required and perhaps some fiddling with the fit, but the components are relatively simple and lay relatively flat. It wouldn't be too hard at all.
Unfortunately, I believe most current Qi charging solutions are relatively low amperage. This would make for a pretty slow charge on the power hungry Nexus 7. Not too bad it you're using it as an overnight charger, but nowhere near as fast as a 2 amp charger. It's possible that you'll find an inductive charger with a higher current output but if you're looking for that it might be easier to build one from scratch,
I did the Touchstone mod on my GNex. It only puts out .56 Amps. Their are kernels with "quick charge" that would let it ramp up to 1 amp but that was it. I am wanting to play with it too, but I'm more thinking of making a dock with POGO pins instead.
I gotta say, they touchstone is great for my GNex. I have a touchstone mounted in my car, so it holds it in place & charges. Occasionally the charge connection gets interrupted (hit a bump, etc...) and it takes 10 seconds to restart. I added additional stronger magnets to my case, but still I don't think the touchstone magnets would do very well holding a tablet instead.
Also, additional magnets screw with your compass...
the touchstone also has a strange angle for watching movies on the tablet.
also i dont know if you can make the induction work with 2amps like the asus charger. (which would be awsome for superfast charging)
If you used the pogo pins for this it would disable the audio if using the correct kernel (see my post in accessories). You would have to modify the kernel to disable it stopping speaker audio out (should be just commenting a few lines though).

The Touchstone is adjustable to whatever angle you want.
I can't seem to find the answer I'm looking for anywhere so here it goes..
I am mounting a Nexus 7 in my car with a bluetooth head unit to get sound through my speakers. If I make a dock containing pogo pins to charge the device, can I run those pins to my cigarette lighter so the N7 charges will the car is on? I have a 12v to 5v 3A converter on the way if needed. I really don't want to fry my battery and have to start over.
Could this idea cause any problems? Thanks in advance.
I don't think the pogo pins will charge the device fast enough to keep up with the usage. So if you travel it will slowly deplete. It is a slow charge. People do this though.
You should also look into installing a wireless charger under your battery door so it charges through induction like the Nexus 4. There are videos that walk you through this. Usually they connect the wireless disc up to the pogo pins or to the battery contacts directly.
The N7 will shut off charging once the battery is full, so youd want the power always on through to the cable.
Food for thought. There are numerous threads here in the forums that show people doing this and their findings. I would do the induction charge though for ease of removal and hassle. You can pick up a touchstone charger and disc for probably $20 on eBay. There are specific models to look for and the details would have to be researched.
My buddy did his N7 and he said it was super easy. His only beef was the N7 was too heavy for the included magnets to really keep a secure connection and some people also purchased stronger magnets for under the battery door to fix this. They turned out so strong that the N7 would actually hang simply by the magnets so it kind of "snaps" in place.

Re-posted from Nexus 7 General (2012).
I just bought a new Nexus 7 (2013), it is about a week old.
Last night I left the supplied ASUS charger and micro-USB cable plugged in overnight (fortunately the cable was not connected to the Nexus.) When I woke up this morning the micro-USB plug had literally melted, with plastic oozing out of the plug housing and through the plug itself. Had the cable been plugged in it would have destroyed the Nexus USB connector. I've seen several reports on the web of this scenario but none with a clear explanation of where the "fire" started. See the attachment.
Does ASUS have a problem here? In any case my plan for now is to use a wireless charger, it is too scary to think what would have happened to the tablet had the cable been plugged in.
I've opened a case with ASUS and they've asked me to RMA the cable so they can inspect it.
It just shorted out. No circuit interruption in the brick leads to certain destruction.

Indeed. Makes you wonder why Asus didn't include some time of current limiting circuitry in the charger cube. How much more could that have cost?
Must be a defect, I've left mine plugged to the wall and not into the N7 for weeks at a time, and this never happened. FWIW, I use a wireless charger now, so I don't physically stress the charging port. I use the Nokia DT-900, got it from AT&T for 50% off. They are still on sale for 25 bucks, worth every penny, and charges through even my thick Seidio case.

My previous tablet was a Kindle Fire and its USB port failed after two years of plugging and unplugging the charge cable. That was my clue to get a tablet with Qi charging the next time around......
I already had a charger on order before this problem occurred... Amazon had a PowerBot® on sale for $22 and it works great - charges through a Poetic case without a problem.

Good deal, anyhow I'd be all over ASUS regarding them replacing (free) my charger as you are. Even if I never use it again, though I still use the USB cable that came with it for adb and fastboot and the occasional PTP USB transfer to/from PC.
I ordered the official Samsung wireless cover from Amazon, slapped it on, and then put my Otterbox Commuter series over it - so far so good, everything fits reasonably well.
I go to put my S5 on a wireless charger and it charges. Then stops charging. Then starts charging again. Then stops again. Over and over it repeats this.
I get to thinking the phone is just too far away, so I take off the hardshell of the Otterbox Commuter. Same thing happens again. So I take off the soft shell - now I'm down to just the naked phone, and it's still charging on and off.
I'm using the blackberry folding blade wires, and the chargers found here: http://forum.xda-developers.com/goo...udget-wireless-charger-showdown-5-qi-t2676249
Specifically, the tilted charger and rectangle with LED lights. Both are giving me the exact same on & off problem.
So does anyone know how to fix this? Is it the chargers or something I'm doing? Are the chargers just not generating a strong enough field (if so, which charger can I get that will generate a better field?)
Thanks for any help
EDIT: Clarified that wireless cover is official Samsung

I had the same issue with a cheap receiver I bought off ebay. The receiver was junk. I took it out of the phone and dropped it on the mat and used a multimeter to check my voltages and never got consistent readings. Tried again with the same chinese mat and the official back and no issues at all.

I am having similar issues using a Palm wireless charger I custom made. I believe the issue is the connection from the cover to the pins on the device next to the battery. I am going to try adjusting it. Also, putting the phone in power saving mode before wireless charging seems to help. Think it may have to do with the wireless charging coil not providing enough amps for the phone to keep up. Trying a different cable/wall charger may help.

It could be the output isn't high enough. For the official mat you need to have a 3 amp charger for it to work. And if the output is too low, the phone may be getting confused because it is detecting a current, but not enough of one for it to be registering that it is charging. I have a car charger that has a 1 amp and a 2 amp setting, and when I try it on the 1 amp setting I get the same issue where it connects and disconnects. 2 amp and I get 0 issues.
I have a similar issue. I'm using the official Samsung S-View Wireless Charging Cover with the Nexus 5 wireless Charger. I get nothing when I put them together. I believe the output from the charger is around 2 amps and it works perfectly with my Nexus 5 (surprise, surprise...) Not sure why I don't get any response whatsoever...

Sorry meant to say 2 amp. But you may want to test your mat and receiver and see if it really putting out the 1 amp the other thread said it was supposed to. If you are getting an output of less than 1 amp that the other thread says it should be then that is probably your issue. Unfortunately I'm not able to measure the outputs on either of my mats to give you an idea until later this evening when I get out of work.

I think you may be right; it may well be the mats I have are just junk, both of them, unfortunately.
I opened up the back of the phone, and brushed off the wireless charging prongs, just to make sure they weren't dirty. Put cover back on, put otterbox commuter case back on.
Put it on the wireless charger, it cycles on/off again and again, about once per second. Take off the hard shell, leaving just the soft shell, and it cycles on/off about once every five seconds - that is, the interval actually got longer. Take off the soft shell, down to a naked phone, and works after cycling on/off about 5 times, then it settles down and stops cycling.
On another charger, the tilted qi charger, it'll charge if the phone is naked, but if I put even the soft shell of the Otterbox Commuter on it, it'll cycle a few times then just not charge at all.
I'm not sure this is a connection problem with the prongs, or a problem with the wire/charger. I think it has something to do with the field that the qi charger is generating. Since I don't know jack about the qi standard, can anyone tell me if all qi fields are equal? That is, do higher quality qi chargers produce a larger or strong field than cheap units?
Like I said in the OP, these are all very cheap chargers, $15 at most, and I'm wondering if that may be the cause.

I use the 2A charger that came with the phone with the CHOETECH pads. The insert is the CHOETECH mat inside the cover. The pad is rated 2.1A input, 1A output. My phone cycles on-off occasionally when the phone hits 100%. I use the Otterbox Defender case.

Interesting, so could the problem be due to just using a cheap generic? Seems that the cheap ones may be generating a smaller or weaker field?
Just wanted to post an update - bought a more expensive charger, one with 3 coils instead of the 1 that was in my other two - and now it charges fine, right through my Otterbox Commuter case.
So to anyone else having this problem - the field generated doesn't seem to be big enough to penetrate the Otterbox Commuter with just one coil, you need 3 or so.

it's not the problem with the coil, they give out the same current, it's because the angled charger is a cheap and nasty one, and the flat one is just a fake one, the official one cost alot more.
3 coils only give you a wider surface detection, the current is just the same as a single coil or a 7 coils.
The 3 coils charger you have is a rebadge of powerqi T300 which is a highly recommended one.
